This is my first time trying out KivyMD. I have the following kivymd bottomnavigation tabs. I’m trying to get the name of the tab that is pressed such that I want to display a datatable etc in one of the tab, some profile functionality in another tab etc. However, when I’m trying to use the 

on_tab_press
event in the 
MDBottomNavigation
, it works. However, it gives me an object instead of the actual value (the tab name that is pressed). In the below 
main.py
, the 
on_tab_press
function gives me the following. How do I get the name from the 
on_tab_press
event?

print(type(args[0])) - <class 'kivymd.uix.bottomnavigation.MDBottomNavigationItem'>
print(*args) - <MDTab name='screen1', text='tab1'>

main.py

from kivymd.theming import ThemeManager

class MainApp(MDApp):

    def build(self):
        theme_cls = ThemeManager()
        self.root = Builder.load_file("main.kv")
        return self.root

    def on_tab_press(self, *args):
        print(type(args[0]))
        print(*args)
        # returns 
        # <class 'kivymd.uix.bottomnavigation.MDBottomNavigationItem'>
        # <MDTab name='screen1', text='tab1'>

main.kv

<BottomNav>:
    #name: 'hello'
    BoxLayout:
        orientation:'vertical'

            MDBottomNavigationItem:
                name: 'screen1'
                text: 'tab1'
                #icon: 'language-python'
                on_tab_press: app.on_tab_press(*args)
                #on_tab_press: app.current = 'home_screen'
